Keuka Energy LLC (https://keukaenergy.com/) develops high solidity wind turbines rotating at low speed while the expected CP is relatively high.
At the opposite a two-bladed rotor like that of MTOsport autogyro (figure 1 and table 2) has a low solidity of 3 %.
The thrust is used, as for an AWES using it:
For an AWES both options can lead to some advantages. A low solidity autogyro rotor can be suitable when the thrust is used as for yo-yo systems, allowing both lightness and lifetime.
